Encrypt, Decrypt, Bruteforce CaeserCipher

CaesarCipherJava

• Deciphers/Ciphers Text by shifting the alphabet

• Written in Java

• Encrypt

• Decrypt

• BruteForce

• Console

• GUI

Console Programme

Encrypt

• let's write a message that is encrypted so no one can see it!

 CaesarCipher cipher = new CaesarCipher(); // Create an Object of the class
 
 /**
 * param text Text that you want to encrypt
 * param shift Amount of alphabet shift
 */
 cipher.encrypt("I don't want to see you!", 1); 

Output: J!epo(u!xbou!up!tff!zpv"

Decrypt

• Now lets try to decrypt this 'J!epo(u!xbou!up!tff!zpv"' with our tool!

 CaesarCipher cipher = new CaesarCipher(); // Create an Object of the class
 
/**
* param text Text that you want to decrypt
* param shift Amount of alphabet shift
*/
cipher.encrypt("J!epo(u!xbou!up!tff!zpv\"", 1);  // added \ so it doesn't break the format/programme

Output: I don't want to see you!

Pretty cool right?

Bruteforce

• We can take the lazy route and bruteforce it, we will take the same example from the decrypt

 CaesarCipher cipher = new CaesarCipher(); // Create an Object of the class
 
/**
* param text Text that you want to decrypt
* param shift Amount of alphabet shift
*/
cipher.bruteforce("J!epo(u!xbou!up!tff!zpv\"");  // added \ so it doesn't break the format/programme

Output: "I don't want to see you! and a bunch of other jumbeled text "
